How I can show the scrollbar as needed?

How I can show the scrollbar as needed?

Hi,

Sorry if I ask a duplicated question.

What I am looking for is: how to show the scrollbar when it is needed
(and hide it when it is not).

I read relevant threads in the forum, and already learned that I could
use DOCHOSTUIFLAG_SCROLL_NO flag to hide the scrollbar. But I still
don't know how to decide whether to show it or not.

Any suggestion would be deeply appreciated!

A little clarification: what I mean by "needed" is that I want to show
the vertical / horizontal scrollbar if and only if the page is
higher / wider than the window of the WebBrowser control.

document.body.scroll="auto";

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly 
overhead. -- RFC 1925

Re: How I can show the scrollbar as needed?

Hi, Igor. Thanks. :) Your advice are really helpful!

One (ok, actually two) more question:

1) In some cases, IE opens pop-up windows which are without address
bar and scrollbars. For example, running the following script will
generate one:

---------------------------------------------------------------------------------------------------------------------
window.open('dest.htm', '', 'height=300,width=400,left=500,top=200',
false);
---------------------------------------------------------------------------------------------------------------------

With the WebBrowser control in my application, I get an NewWindow3
notification when running the above script.

The dwFlags is 0x00040006, that is, NWMF_SUGGESTWINDOW | NWMF_FIRST |
NWMF_USERINITED.

I want to create an appropriate window (with or without address bar,
just like IE) in my application for this event. However, I think we
cannot judge from the flag that this new window is a pop-up window
without address & scrollbars, or it is a normal window.

Is there any other information that I can use to make this
judgment? :) What has IE done to make the decision?

2) (Still using the scenario above: run the window.open(...) script in
my WebBrowser control and get a NewWindow3 notification)
I notice that if I create a new WebBrowser control, and pass it back
in the NewWindow3's IDispatch** parameter, this WebBrowser will have
no scrollbars (even after I ask it to navigate to another location.)

How does this happen? Does the parent WebBrowser control implements
the IDocHostUIHandler::GetHostInfo() interface and set
DOCHOSTUIFLAG_SCROLL_NO?
How can I enable its scrollbars again?

Thanks very much!

Yes, it honors parameters in window.open(), not necessarily those of the 
page it loads.

Perhaps. I'm not sure how precisely this is implemented.
